C Call a method in a new thread

Question

I am looking for a way to call a method on a new thread  using C     For instance  I would like to call SecondFoo   on a new thread  However  I would then like to have the thread terminated when SecondFoo   finishes   I have seen several examples of threading in C   but none that apply to this specific scenario where I need the spawned thread to terminate itself  Is this possible   How can I force the spawned thread running Secondfoo   to terminate upon completion   Has anyone come across any examples of this

Asynchronous version   private async Task DoAsync         await Task Run async      gt                  Do something awaitable here

Does it really have to be a thread  or can it be a task too   if so  the easiest way is   Task Factory StartNew      gt  SecondFoo

Unless you have a special situation that requires a non thread-pool thread  just use a thread pool thread like this   Action secondFooAsync   new Action SecondFoo    secondFooAsync BeginInvoke new AsyncCallback result   gt                    result AsyncState as Action  EndInvoke result               secondFooAsync      Gaurantees that EndInvoke is called to take care of the clean up for you

As far as I understand you need mean terminate as Thread Abort   right  In this case  you can just exit the Foo    Or you can use Process to catch the thread    Thread myThread   new Thread DoWork    myThread Abort     myThread Start       Process example   using System  using System Diagnostics  using System ComponentModel  using System Threading  using Microsoft VisualBasic   class PrintProcessClass        private Process myProcess   new Process        private int elapsedTime      private bool eventHandled          Print a file with any known extension      public void PrintDoc string fileName                 elapsedTime   0          eventHandled   false           try                          Start a process to print a file and raise an event when done              myProcess StartInfo FileName   fileName              myProcess StartInfo Verb    Print               myProcess StartInfo CreateNoWindow   true              myProcess EnableRaisingEvents   true              myProcess Exited    new EventHandler myProcess Exited               myProcess Start                       catch  Exception ex                        Console WriteLine  An error occurred trying to print    0          n    ex Message  fileName               return                        Wait for Exited event  but not more than 30 seconds          const int SLEEP AMOUNT   100          while   eventHandled                        elapsedTime    SLEEP AMOUNT              if  elapsedTime  gt  30000                                break                            Thread Sleep SLEEP AMOUNT                           Handle Exited event and display process information      private void myProcess Exited object sender  System EventArgs e                 eventHandled   true          Console WriteLine  Exit time      0  r n                 Exit code      1  r nElapsed time   2    myProcess ExitTime  myProcess ExitCode  elapsedTime              public static void Main string   args                    Verify that an argument has been entered          if  args Length  lt   0                        Console WriteLine  Enter a file name                 return                        Create the process and print the document          PrintProcessClass myPrintProcess   new PrintProcessClass            myPrintProcess PrintDoc args 0

If you actually start a new thread  that thread will terminate when the method finishes   Thread thread   new Thread SecondFoo   thread Start      Now SecondFoo will be called in the new thread  and the thread will terminate when it completes   Did you actually mean that you wanted the thread to terminate when the method in the calling thread completes   EDIT  Note that starting a thread is a reasonably expensive operation  Do you definitely need a brand new thread rather than using a threadpool thread  Consider using ThreadPool QueueUserWorkItem or  preferrably  if you re using  NET 4  TaskFactory StartNew

Once a thread is started  it is not necessary to retain a reference to the Thread object  The thread continues to execute until the thread procedure ends   new Thread new ThreadStart SecondFoo   Start
